Danger of emails that can be traced

Bill Thompson, a journalist who regularly appears on the BBC World Service programme Digital Planet and who teaches at London's City University, thinks we ought to be more careful about our emails. Once someone emails from a work address then that person can never be guaranteed anonymity in future, he says, "because it is so easy for employers or the police to get access to email traffic records." His advice? Take the trouble to encrypt. (Via BBC)
